During the Google Buzz launch event, Brin spoke of being a big fan, even using it to gather opinions internally at Google about a New York Times opinion piece he was writing about Google Books.

Now that Buzz is available to the public, will Brin be participating? At the TED Conference in Long Beach, he told me that he might. The key issue for him and a number of Googlers is that the Buzz accounts they’ve used so far have only been for discussions within Google. Those account either need to be enabled to tap into the public version of Google Buzz or Googlers will have to open new accounts. That’s something Google’s looking at.
